Types of industrial AC units

Industrial air conditioning (AC) units serve vital roles in regulating indoor temperatures and ensuring air quality. Some industrial air conditioner applications include:

• Large Building: A huge volume of air needs to be cooled for comfortable living.
• Critical Infrastructure: Maintaining a temperature range is essential for sensitive equipment, such as data centers and server farms.
• Industrial Processes: Controlling temperature is necessary for specific manufacturing processes and the stability of chemical reactions.
• Cleanroom: Achieving temperature control and filtration is essential to meet class standards and foster sterile environments.
• Restaurants and Hotels: Multiple rooms and a high level of occupancy create the need for widespread temperature regulation and dehumidification.
• Supermarket: Storing perishable food at low temperatures is necessary to maintain the integrity of refrigeration systems and prevent spoilage.
• Office: Creating a comfortable and productive workplace is essential for temperature regulation in commercial spaces.

Besides this, below are some of the most common types of industrial AC units used to regulate air temperature and humidity in workspaces.

• Split industrial air conditioner: An industrial split AC typically consists of an indoor and outdoor unit. While the indoor unit is mounted on the wall or ceiling of a room, the outdoor unit is installed on the ground or roof. Refrigerant piping connects both components. The industrial split AC cools rooms of large buildings. The indoor unit comes in small-to-big sizes, takes up floor space, or is part of an open/high ceiling. Ducted units use ducts to distribute cool air, while ductless (mini-splits) directly cool only one or a few rooms. Mini-splits have smaller indoor units. The outdoor component has the compressor and condenser coils.
• Floor standing air conditioner: Floor standing AC units feature tall, box-like designs that permit placement against any wall or corner. A floor standing industrial AC operates like a split unit but with all components housed in a single unit. The entire system is stored within the indoor room. These units are mainly used to cool server rooms that house computing machines with high energy demands. It can also be a temporary solution while waiting for permanent cooling options.
• Portable air conditioner: A portable air conditioner stands on the floor like a small fridge and is moved easily from one indoor space to another. While indoor AC units have to be placed close to windows, portable air conditioners need ducts to let hot air out through the window. Some models have double ducts that improve cooling speeds.
• Centralized air conditioning: Centralized air conditioning is used to cool huge open workspaces and the typical way of distributing cool air from one compressor to many indoor rooms/units using refrigerant pipes. This complete outdoor unit/entire system stored outdoors option is usually done on rooftops, but it can sometimes also be done on the ground with a large back-and-white box. Roof-mounted units are mostly seen in commercial/industrial applications where ducted systems are used. A centralized system offers more energy efficiency than split and standing units used to cool individual rooms.
• VRF air conditioner system: An air conditioning system that uses a single outdoor unit to cool multiple indoor evaporator units is known as a Variable Refrigerant Flow (VRF) system. The outdoor unit pumps small amounts of refrigerant to the indoor evaporators to absorb heat in a building, thereby cooling it. The outdoor condenser can be up on a roof or on the ground like a box. Indoor evaporators might be ducted hard material that travels around the entire room or soft duct/mini that travels to specific areas to ducted floor units. VRF systems have inverter compressors that change motor speeds to meet varying demands.

Specification and Maintenance

Specifications for an industrial AC unit show varying capabilities among different models. Here are some key specs to check when buying:

• Unit Size: The overall dimensions of the indoor air handler and outdoor condenser need to fit within available spaces. A rooftop unit will have a big box-shaped outdoor cabinet with a deck mounting frame.
• Cooling Capacity: Measured in tons, this indicates how much heat the unit can remove from inside a building. Larger commercial spaces require higher tonnage to achieve adequate cooling.
• Energy Efficiency: An industrial AC's efficiency is expressed by its EER or SEER ratings. Higher ratings mean more efficient power usage for cooling capacity. Choosing a unit with a high EER/SEER can reduce electricity bills.
• Airflow Volume: Measured in cubic feet per minute (CFM), this spec reflects how much indoor air the evaporator will circulate. Larger units generally move a higher CFM volume to accommodate bigger spaces.
• Refrigerant Type: AC systems use specific kinds of refrigerants, like R22, R410A, or others. Contractors must match the refrigerant with existing ones in a building for compatibility during service or replacement.
• Controls and Features: Options like programmable thermostats, remote monitoring, variable-speed fans, and zone dampers allow more precise management of an industrial unit's performance and energy use.
• Warranty: Typically, major components like compressors, coils, and fans are covered for 5 years. Extended warranties may cover labor costs too. Check the terms and duration when purchasing.

Proper maintenance routines help keep industrial air conditioners running optimally. Here's an outline of suggested tasks and their frequencies:

• Monthly: Inspect/clean indoor coil blowers. Check refrigerant pressures. Examine filters and wash/replace. Clean drain lines.
• Quarterly: Add oil to fan motors per manufacturer specs. Verify thermostat functions. Inspect ductwork. Check safety controls.
• Every 6 months: For rooftop units – brush clean condenser coils. For split systems – inspect both indoor and outdoor units. Check belts for appropriate tension and alignment.
• Annually: Inspect and adjust refrigerant charge. Lubricate all moving parts. Inspect contactors, relays, and connections; tighten as needed. Calibration of commercial thermostats. Inspect the integrity of the housing. Ensure proper airflow and temperatures throughout the system.

Uses of industrial AC units

Like most air conditioning units, the industrial AC brings comfort to working and living spaces. However, the degree of importance makes many applications need the unit to function to perform various critical tasks.

For starters, an industrial AC unit helps to keep employees working under a conducive environment where temperatures are within normal ranges. This is especially true for warehouses and factories with equipment that generates a lot of heat or those that have to deal with high ambient temperatures.

In addition, an industrial air conditioner is crucial in maintaining product quality. Many industries rely on consistent temperature control to achieve this. Products such as pharmaceutical drugs and chemicals are more demanding, requiring precise temperature control if they are to stay within their ideal parameters.

Food and beverage factories also need industrial ACs to preserve products like frozen yogurt, ice cream and meat. Likewise, data centers and server rooms use industrial air conditioning to prevent servers and other sensitive electronic equipment from overheating, which could lead to malfunctions and system crashes.

Industrial AC units play a significant role in extending the lifespan of machinery and equipment. Many types of machinery and manufacturing equipment are sensitive to temperature. Extreme changes could jeopardize their integrity and functionality, and air conditioners help cool and dehumidify the air to prevent corrosion and overheating.

Finally, industrial air conditioners help avoid costly downtime by ensuring uninterrupted production processes. Unexpected shutdowns could easily be caused by overheating machinery, prompting a need for immediate repairs and replacements. Cooling systems in industrial settings eliminate such risks by keeping machines cool.

How to Choose Industrial AC Units

When choosing industrial air conditioning units, it is essential to evaluate the needs of the building first. Factors like the building's size and the amount of space to be cooled should be considered. Users should determine the required capacity by measuring the square footage, insulation, ceiling height, and window areas. Once this is done, users can select an AC unit with the correct cooling capacity.

Next, users should consider the layout of the building. Whether rooms need units or a long ducting system is required to cool the entire space, users should look for an air conditioner suitable for a zoned or open layout.

If noise levels are a concern, users should check the decibel (dB) ratings of different industrial AC units. Because large machines may not need to be quiet, indoor and outdoor units may have different noise levels. Machines with higher energy efficiency ratings use less electricity. So, apart from the upfront cost, users should also consider future energy expenses.

Indoor units may need to be resistant to dust and corrosion. Therefore, people with different installation requirements should ensure that the chosen air conditioner has the appropriate IP rating to provide adequate protection against environmental hazards.

If users have additional needs, such as air purifying or dehumidifying, they should ensure that the selected industrial AC unit has the necessary functions and features to provide the desired indoor air quality.
